(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. L, 1313.)

To all whom it may concern:

Be it known that I, ALPHoNs ZIPFEL, a citizen of the Republic of Switzerland, residing at Lachen, Switzerland, have invented certain new and useful Improvements in Weaving-Healds and Processes for Manufacturing the Same, (for which apsilications have been filed in Switzerland,

eptember 26, 1914, Patent No. 69,158; Germany, October 5, 1914, Patent No. 289,895; Austria, September 20, 1915, Patent No. 7 3,- 428; Hungary, September 23, 1915, Patent No. 69,710; France, September 25, 1915, Patent No. 479,835; England, September 25, 1915, Patent No. 136,48/15, and Pologne, November 13, 1919, app1n. No.7,587/19;) and I do hereby declare the following to be a clear, full, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The present invention relates to improvements in healds for weaving looms and the like, and the process for manufacturing the same.

Weaving healds forlooms made of double steel wire are already known which have lengthened ears at their ends 'for receiving the heald bars and have a thread eye arranged between these ears. The ears on the ends of the healds have been formed by bending out the double steel wire and winding the ends about the shaft and securing them to the latter by soldering.

These healds have the disadvantage that the ears are thicker than the double strand of wire and therefore take up too much space as regards the juxtaposition of the healds on the heald rods, and consequently also increase the total weight of the healds. Also, it can occur in such constructions that thehealds owing to some thickened portion may catch and remain suspended when the shafts are lifted or lowered and consequently interfere with one anothers correct predetermined movement.

It has been suggested in the case of healds acting as feelerrods in warp stop motions, to use instead of the wire ears thin steel plates having ears formed upon them and which lie at right-angles to the heald rods. It has however not been found possible to obtain a suitable method of connecting the small plates with the double steel wire which will satisfy all desired conditions.

The present invention-relates to a means whereby a loom heald may be made of double steel wire and have ears at both ends of the heald shaft for connection to the heald rods, such ears being in the form of steel plates. The invention further relates to a process for manufacturing such articles.

According to the present invention the heald shafts are arranged to lie with the bent out ends of the wire parts engaging in the correspondingly shaped slots in small plates and these parts of the wire'are connected with the small plates by soldering so that the heald at the connection point between the'healdshaft and steel plate will at the most not be thicker than an ordinary wire of the wire shaft.

These healds are formed by splitting the double wire and bending outward the tWo ends of the wire shaft, placing these inthe correspondingly shaped stamped out slots of the small plates of steel or the like. The bent ends of the wire shaft are then pressed into the notches in the steel plates and subsequently connected to the plates by soldering. v

The invention is more particularly described with reference to the accompanying drawings, in which Figures 1 and 2 show one form of construction by way of example in side and front vlew respectively, while F igs. 3 to 10 show different steps in the 1 process of manufacturing the articles,

Fig. 9, being a section on the line A-B of Fig. 5, and Fig. 10 being. a section on the line CD of Fig.

The loom shown in Figs. 1 and 2, which may also be used as a feeler rod for warp stop motions consists essentially of a shaft 1 formed of double steel wire or the like which at both en s is P i wit this r a s1ot5 ending inwardly in a circular broadened portion 6 in which the ends of the wire shaft 1 are arranged with the parts 7 and- 8 spread out therein (see Figs. 5 to 9). The small plates are connected with the parts 7 and 8 by solder and the heald at the connection between the heald shaft and the small plates isonly as thick asthe thickness of a single wire or the wire heald.

The loom healds are made as follows By means of a stamp the slot 5 having an enlarged portion 6 is stamped out of a steel plate 2 or the like (Fig. 3). Then by means of a suitable instrument the wire ends of a the heald shaft, the two wires of which are soldered togetherin known manner, are separated and bent around into annular form. The shaft, of the heald is at this place split alongits length for a short distance so that springy portions 7 are formed on the two semiannular-portionsS (Fig. 4), which will correspond in shape to the cut-away portion 5, 6 of the small late 2.

The ends 7 an 8 of the wires forming the heald thus shaped are pressed into the slots 5 and 6 of each of the small plates 2 under pressure 50 that the two springy portions 9.and the two annular halves 7 are pressed one toward the other (5 and 6). The pressing in of the parts i such that the parts 7 and 8, after bein pressed in, lie as much onone side of t e plate as on'the other (see Figs. 6 and 9). As the parts 7 and 8 of the shaft tend to spring apart from one another they will hold'the. small plates sufficiently securely to prevent displacement of the parts during transporting of the shafts with the small plates from one point to another. Consequently it is possible to pass the shafts with the plates to a soldering apparatus by mechanical means where the arts 7 and 8 are soldered to the plates 2.

he space inclosed by the semi-annularpor- -tions 7 as also the space between these,-and the parts 8 and the plates 2 will be filled with solder (Fig. 10) and finall the excess solder will be removed or wil be leveled between the parts 7 and 8.

By this means the shafts at the lace of connection with the plates 2 will at t 1e most be only as thick as a single wire of the double wire heald. It is therefore possibletoarrange a greater number of healds than hitherto possible along a shaft, or alternatively to provide a greater free space between the healds and thereby to prevent a mutual i t en r n rence bet e n th plate may be formed longer than the corresponding ears in previous constructions of wire healds so that thehealds may be given greater motion and consequently an lmproved guiding of the heald rods may be obtained; 7 The cut-away portions in the steel plates 2 and the shape of wire end of the heald pressed into them may are other shapes then those shown aarticularly by way of' example; The smal plates 2*at the lower ends of the healds. can be extended for a greater length unbroken in order that when 1.
